No, it doesn't require it. When I was speaking of AppleShare, I was speaking of the client Mac that was connecting to another Mac running EasyShare.

I agree, even if it loaded on the 128K, it wouldn't do you any good, since you can't share a MFS disk.

I have a sinking feeling this is going to require the 128K ROM, or a Mac 512Ke at minimum. That's OK, because I know of no other way to make a stock 512Ke a file server, so it's still a big find.
